“…In [14], [15], and [16] commercial off-the-shelf pulse radar sensors of a frequency range of 3.1 GHz to 5.3 GHz are used for surface and subsurface imaging. A platform using a 24 GHz frequency modulated continuous wave (FMCW) radar with 250 MHz bandwidth for full interferometric SAR imaging and processing is evaluated in [17]. An approach for UAV-based mine detection using ground penetrating synthetic aperture radar (GPSAR) is presented in [9].…”

Modern consumer and industrial unmanned aerial vehicles (UAVs) are easy to use flying sensor platforms. They offer stable flight, good maneuverability, hovering, and even waypoint flights in autopilot mode. For stabilization and localization sensors such as internal measurement units (IMUs) including gyroscope and accelerometer, barometric sensor, and global navigation satellite system (GNSS) are used. To sense the direct environment of the UAV, for instance for collision avoidance or fully automated flights, additional sensors are needed. State-of-the-art combinations of infrared sensors, ultrasonic sensors as well as vision based sensors (monocular and/or stereo vision) capture the close vicinity. Using radar sensors is advantageous, as they are able to directly sense range and velocity and are not prone to lighting conditions and contrast. With the help of a multi-channel radar, the angular information can also be extracted. UAVs can lift a considerable payload with respect to their size. All these characteristics combined with radar sensors make them a promising tool for a large variety of applications.

“…With a radar-based altimeter these limitations can be overcome, as radar systems are robust against weather and lighting conditions. UAVs equipped with radar sensors are presented in [3] at 24 GHz with 250 MHz bandwidth and in [4] at 94 GHz with 1 GHz bandwidth, used for synthetic aperture radar (SAR) remote sensing.…”

For multi-copter unmanned aerial vehicles (UAVs) sensing of the actual altitude is an important task. Many functions providing increased flight safety and easy maneuverability rely on altitude data. Commonly used sensors provide the altitude only relative to the starting position, or are limited in range and/or resolution. With the 77 GHz FMCW radar-based altimeter presented in this paper not only the actual altitude over ground but also obstacles such as trees and bushes can be detected. The capability of this solution is verified by measurements over different terrain and vegetation.
